Todo

1. use shorthand for default slots
2. Some test failures are seemingly caused by <ds-*> not handling the new syntax well. If so, and since they are supposed to be refactored out anyway, this might be a blocker. Turns out, components are not the cause. Just didn't understand the new syntax, fully. (see comment)
